TYPE-BAR FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Oct. 31, 1905.

Original application filed November 21, 1904, Serial No. 233,586.Divided and this application filed March 16, 1905. Serial No. 250,377.

T0 (025 whom it may concern:

Be it known that I, CHARLES J. BELLAMY, a citizen of the United Statesof America, residing at Springfield, in the county of Hampden andCommonwealth of Massachusetts, have invented a new and useful Type-Barfor Type- Writers, of which the following is a specification, the samebeing a divisional part of my application for Letters Patent filed inthe United States Patent Office November 21, 1904:, and seriallynumbered 233,586.

My invention relates to improvements in type-bars for type-writersdesigned to produce a plurality of original impressions, and comprises atype-bar equipped with more than one character of the same kind; and theobject of my invention is to provide a typebar capable of imparting in asingle movement a plurality of original impressions. I attain thisobject by the means illustrated in the accompanying drawings, in whiclFigure 1 is a face view of a type-bar embodying my invention, suchtype-bar being applicable to the Franklin style of type-writer; Fig. 2,a side view of a portion of said typebar, showing two of the charactersthereon in contact with two platens; Figs. 3 and 4, face views of two ofmy type-bars adapted for use in a Remington or similar machine, and Fig.5 a view of a type-bar adaptable for an Oliver machine.

Similar letters refer to similar parts throughout the several views.

Referring first to Figs. 1 and 2, it will be observed that a type-bar ais there shown which may be pivotally mounted in the frame of a machineand operatively connected with the corresponding key and that such barhas two plates 6 and Z) afiixed thereto with upper and lower caseletters or characters thereon, the letters or characters upon one platebeing duplicates of those upon the other; but the style of letter orcharacter may differ as between the two sets. 0 represents the pivotalend of the barthat from which the same is operated. The word character Iwish to be understood as applying to any letter, figure, or symbol thatmay be used in connection with type-writers. One set of characters onthe bar a is located at or adjacent the free terminal thereof, while theother set is located at such a distance from the first as to bringcorresponding or duplicate characters exactly onto the centers of thetwo platens, with which the machine acters themselves are the same.

equipped with these type-bars must be provided, when the bar isdepressedthat is to say, the two small os on the bar shown will bothstrike the platens on vertical lines cutting the axes of the same, andwhen the platens are shifted the capital Os will strike them at the sameplaces. Two such platens are indicated at (Z and d in Fig. 2.

Instead of having the characters on plates or strips, as shown in thedrawings, they may be imposed directly on the type-bars in some cases.

By the word duplicate as applied to characters another character of thesame kind is meantthat is, a second capital A, a second small a, asecond-,&c. Therefore it will be seen that one type-bar may carry two As andtwo as, another two 48s and two &S, and so on, although the same kind offaces need not necessarily be employed, provided the outlines or char-For instance, one character might be Roman and its duplicate italic.

In Fig. 2 the bar a, equipped with the characters o and O in duplicate,is shown in its depressed position with the os in printing positions onthe platens (Z and cl, and as a result of this two impressions of thesame kind are simultaneously made in practice on the platens or on papercarried thereby, the action of the character 0 on the plate Z) being thesame, so far as the act of printing is concerned, as is that of thechar' acter 0 on the plate 6.

A ribbon or other inking medium is to be used with the improved type-barwhere the same is employed in a machine for ordinary purposes.

The same general construction of type-bars is present regardless of themake of machine with which they are incorporated, although of coursethere will necessarily be some structural modification required to adaptthe typebars to different machines. The angle of the bend in type-barssimilar to that shown in the first two views varies according toposition relative to the longitudinal center of the machine, thosenearest such center having the least deflection from a straight line,while those at the extreme ends of the machine have the greatestdeflection and those coming between are bent more than the central onesand less than the outer ones, according to the position occupied. riallydifferent from those already in typebars now to be found in the Franklinmachine.

As before intimated, the arrangement of characters on the type-bars willdiffer in differentstyles of type-bar machines. Two bars a, adaptablefor the Remington machine and other machines in the same class, areshown in Figs. 3 and 4:, the character-plate b in the first standing atan angle with the bar itself, and such plate in the second beingparallel with the bar. 0 is the pivotal end of the bar (0. Thesetype-bars differ only from those now in use in the length ofcharacter-plates and the duplication of the characters. In this machinethe basket will have to be enlarged more or less. To adapt myimprovements to the Remington, the type-bars must be so shaped anddisposed as to present a character for impression on each platen and atthe same time so arranged that an individual type-bar can perform itswork without interlocking or coming into contact with any othertype-bar. Segmentally and oppositely disposed crescent groups oftype-bars are perhaps the simplest to arrange, as the Oliver, it beingonly necessary to introduce a parallel platen on the same horizontalplane and to make the bow-shaped type-bar in twin form, as shown in Fig.5, in which (0 represents a bar hav ing a double bow-shaped head 0/, towhich the two character-plates 7/ are attached, the characters on eachof which latter being duplicates of those on the other. The type-bars inthe Williams style of machines can be very easily adapted to the newwork by merely extending each of them on the same plane and These bendsare not mate at the same angle to the horizontal axis as before. TheUnderwood and Franklin typebars are very much alike.

I do not wish to be limited to a mere duplication or the addition of asingle type character whereby two original impressions only areobtained, since it is obvious that when deemed advisable by providingthe requisite number of characters on the type-bars and installing themin a suitable machine three or even more original impressions may bemade simultaneously. Hence the term duplicate or its equivalent is to beunderstood as meaning any number more than one.

WV hat I claim as my invention, and desire to secure by Letters Patent,is

1. As a new article of manufacture, a typebar provided with a duplicateof each character thereon, so arranged as to make a simultaneousimpression in duplicate thereof.

2. As a new article of manufacture, a typebar having duplicatecharacters imposed on the working face, side or edge thereof, andadapted to make simultaneous duplicate impressions.

3. As a new article of manufacture, a typcbar provided with a pluralityof types on its working face, side or edge, said types being arranged tosimultaneously make duplicate impressions.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
